A computing device includes an interface configured to interface and communicate with a dispersed storage network (DSN), a memory that stores operational instructions, and a processing module operably coupled to the interface and memory such that the processing module, when operable within the computing device based on the operational instructions, is configured to perform various operations. For example, the computing device generates a prioritized request that includes at least one of a task for execution or a priority level based on information stored within a storage unit (SU) of a plurality of storage units (SUs) implemented within the DSN. Note that the information corresponds to a data object that is related to a set of encoded data slices (EDSs) that are distributedly stored within the DSN. The computing device then transmits the prioritized request to the SU and receives, from the SU, a response to the prioritized request.
